3 broken belts, 3 sleds, in 2 days

[Freeride1]

Apparently there is something to all the hype around the EASY break in miles for the Quick Drive Belt. I thought it was more of a heat thing that was coausing them to delaminate not an overload issue.

My sled and 2 of my friends all stripped our belts this weekend having way to much fun riding a closed ski area out here. I was checking the temp of my belt reqularly and it never got really warm. I could just barely feel heat when I would check it with my bare hand. I even tried to trail ride it friday night to get some easy miles on it. I got it to 80 miles with the first 35 of them riding pretty hard on the mountain. I think I really hurt it when I tightened my track to get it to stop ratcheting on deep climbs and after I hit a water bar jump while climbing.

It was not feasable to trail ride until now because there was no snow on any of the trails. The only place that had snow was on the mountain. This week we got snow around the house so I can go ride after work on the goat paths locally and break in the next belt before we go out west in 2 weeks.

I really wish Polaris had warned me about this delicated break in procedure when I picked the sled up. The only warning I saw was something about riding it fast and keeping the scratchers down on less than 3 inches of snow. Thiere should be a huge warning tag hanging from the throttle explaining it is GAURANTEED TO BREAK if we don't figure out how to ride it 100 miles before we go to the mountains.

This is what my belt looked like after I tightened the track and did a 30 second WFO climb with a wind blown water bar at the top. The water bar was the kiss of death to the belt after that climb. Same thing happened to two of my friends I was riding with that day.

BREAK IN YOUR BELT!

that'll teach u guys to sneak off with out inviting the rest of us
hope all goes better with the new belt break in .

100 miles

100 mile break in? Does anybody else find that to be a little ridiculous?

 

[Rixster]

What about breaking in your motor? I am thinking that the way I break in a new motor I wouldn't have a issue with this belt thing. It seams like people don't break in anything any more.

100 miles no more than half throttle!!!!!!! ill stick with my ac

 

[TGitt]

So how was it getting it home?

Mine looked worse then that at 210 miles and I took the time to break it in.

Yes I do!

 

[samtarolli]

That ratcheting was probably your belt. I was hearing ratcheting before mine went out

I'm wondering if you would be willing to do a test for me on your failed belt.

Boil some water in a large pan and put part of the belt in the water that is boiling for 10 minutes.

Pull it out and tell me if the belt teeth became soft or not???

Test related to this post I put up a while back.

From the Gates "Synchronous BeltFailure Analysis Guide"

Heat Degradation
When rubber belts operate at elevated temperatures (greater than
185°F) for prolonged periods of time, the rubber compound gradually
hardens resulting in back cracking due to bending. These cracks
typically remain parallel to the belt teeth and usually occur over land
areas (in between belt teeth).

High-temperature rubber belt constructions are available for belt drives
that must operate in high-temperature environments. These special
belt constructions help to improve belt service. To determine if a special
high-temperature belt construction will improve the belt performance in
specific applications, contact a Gates Representative.

Belts generally fail due to tooth shear , which can lead to tensile cord fracture.

The body material used in urethane belts such as Poly Chain® GT®
Carbon® belts is thermoplastic, meaning it has a melting point. When
subjected to environmental temperatures in excess of 185°F, the teeth
may begin to soften and deform. In addition, the tensile cord to urethane
adhesion loses its integrity. Figure 18 illustrates a Poly Chain® GT®2

See ya have fun on your AC.....

The belt will be soft I'n boiling water at 210 degrees F at sea level. Something is happening with the drives if there getting that hot. Gates is the the best I'n the HVAC world but sleds I don't know and thats not a valid test unless your testing a radiator thermostat. Boiling water?

 

[mountainhorse]

Yes... boiling water... Look at the quote in my last post here.... 185 degrees F is what Gates is claiming on their belts as the trouble mark.

The gates carbon belts on the C3 and CMX are not getting soft at that temp... different compound... I'm curious what the Polaris is doing at that.

Who knows if Polaris is using Gates or another brand... and what model or spec they are calling for in the QD though. There are no gates numbers or logos on the belts.

With brake heat, exhaust heat and belt-generated heat in the system (sizzling top sprockets as witnesed by some) ... I'm curious about this topic....

Happy New year!!!

[sidehil]

Mtn H I don't mean any bad but boiling is 25 degrees above their trouble mark. You are a good sled head and have helped a ton. I got 5 miles on my cousins pro and they rip! But we are not going far until this deal is figured out. Keep up the good work! Happy New Year!

 

[sidehil]

Id put a Fluke recording meter I'n my pack with a tempsensor near the drive. The tools are wireless and an industry standard. You could print out a very nice graph with Fluke Forms.' Hopefully someone at Polaris is doing that as we speak.

 

[winter brew]

I dont buy the lack of "break in" excuse from Polaris for failures.
Will someone breaking belts PLEASE check the runout on the lower pulley? This pulley must be true to maintain constant belt tension.... A little off and the belt is tight/loose as it spins....death for a belt.
I have seen some pulleys that have an obvious wobble. Im betting there is a correlation.
Our shop Pro, ridden hard from mile 1 with 3" track and heavy deep snow with no problems and the pulley spins true. Those losing belts seem to be losing multiple belts regardless of how its being ridden. There is something causing the failure.

I know it sucks but it states clearly in the owners manual how to properly break in the quick drive belt. 100 miles on new quick system but only 30 miles for a new replacement belt. I'm at 25, 75 to go.

 

[Scott]

There are some very silly misconceptions regarding break-in.

Its quality, not quantity.

You don't have to stay under half throttle for 100 miles.

Read up on the threads on here to see what is proper.

 

[HOOCH256]

What I don't get is I have a 500hp AWD eagle talon and I can do 15psi boosted launches spinning all four slicks and running 10's in the 1/4 and guess what it's running a gates timing belt and its holding just fine and I've never heard of one breaking or failure of any kind. Even some guys running down into the 7's at 191mph. So if you ask me I think Polaris is just using a cheap a$$ belt! Be nice for you poo guys if some aftermarket company's would step up to the plate and build some better belts

s sled mfg'er cuting corners with cheap parts? your kidding right?
same factory is probably make the belts and those top quality AC clutches...
